Airtel
Activation of Post Dated Nos

My Company Name is Usra Technologies, I have opted for 5 connection from Airtel, one of my main no. was activated on the billed date but the rest of the nos. were provided 12 to 15 days later but the nos. were activated without my knowledge on the same day as the main no. 9004757575 and billed accordingly.

The rest of the nos should be billed on the day they were provided or the first call made from them.
